Glean

Glean is a leading enterprise AI search platform that connects to over 100 data sources -- including Google Workspace, Microsoft 365, Slack, Salesforce, Jira, Confluence, and dozens more -- to provide a unified search experience across the entire organization. It uses deep learning models to understand permissions, organizational context, and relevance signals, delivering personalized results based on each employee's role, team, and access level. Search results respect existing access controls so users only see content they are authorized to view.

Enterprise teams use Glean to eliminate information silos and reduce time spent searching for internal knowledge. The platform includes a conversational AI assistant that can synthesize answers from multiple sources, generate summaries, and provide citations back to original documents. Glean's administrative controls include SSO integration, usage analytics, data source management, and content boosting rules that allow IT teams to surface authoritative sources for specific topics.

Glean differentiates itself through its people-aware search graph, which understands organizational relationships, expertise areas, and collaboration patterns to improve result relevance over time. Unlike keyword-based enterprise search tools, Glean learns from user behavior -- clicks, bookmarks, and query patterns -- to continuously refine its ranking models for each organization. This behavioral learning layer makes Glean particularly effective for large organizations where the same query from different departments should surface different, contextually appropriate results.
